Fixed #101. #89 may now be fixed as well, needs more testing to confirm. Added drupalgap.pages and modified drupalgap_add_page_to_dom() to add the page_id to drupalgap.pages. Added drupalgap_remove_pages_from_dom(). Changed drupalgap_goto() to watch out for the reloadPage option. Changed drupalgap_goto_generate_page_and_go() to have both of the possible changePage calls pass along any options that were sent initially to drupalgap_goto(). Changed drupalgap.services.user login and logout to call drupalgap_remove_pages_from_dom() on sucess. Changed the user_logout() page callback to return some basic html then modified its hook_menu entry to use a pagechange event handler that will do the actual logout call.
